"disconnecting quattro drive?" - answer

When I had a bad prop-shaft CV in the '84 4KQ I dropped out the shaft, locked
the center diff and drove the car FWD for a week or so while I rebuilt the bad
shaft. Many a quattro Pro-Rally car has finished a stage or even a whole event
running with just RWD/FWD and won! Just try *that* with your 2WDer.
